Aquatic, wetland, and upland areas in and along the Delaware estuary provide a rich variety of habitats, home to many fish, plants, and animals. To read more about what wildlife can be found along the Tidal Delaware Water Trail, check out the Pennsylvania Wildlife Action Plan.
Over a dozen species were historically found in streams throughout the Delaware Estuary. Unfortunately, very few species are found in Pennsylvania, New Jersey, and Delaware today due to a combination of polluted water, toxic spills, over-harvesting for bait, loss of forests along streams, and loss of fish hosts needed for reproduction and dams that block fish passage. The Partnership for the Delaware Estuary is doing important work in protecting and developing the remaining freshwater mussel beds. More Information
